Digital trunking operator Nextel Argentina plans to invest ARS262 million (USD67.5 million) this year in its network and services, BNamericas reports citing local press. The funds will be spent on the expansion and modernisation of infrastructure, as well as the optimisation of systems and processes. As part of the company’s network expansion in 2010, Nextel will provide services to the cities of Balcarce, Tandil, Azul and Olavarria in Buenos Aires province. According to TeleGeography’s GlobalComms Database, Nextel Argentina is a wholly owned subsidiary of US-based holding company NII Holdings. It launched digital trunking wireless services in the 800MHz band in 1998, using a packet-based integrated digital enhanced network (iDEN) platform supplied by Motorola. Whilst it lags behind the market as a whole with around 2% of subscribers, Nextel has established a significant base of business customers, numbering 1.03 million at the end of 2009.
